An Automatic Start-Stop system is used when an engine must start with no one in attendance. The generator set must start, pick up the load, operate the load and stop after the load is removed.Starting the Engine
1. To start the engine when unattended, the engine room temperature must be at least 20°C (70°F) or the engine jacket water temperature must be 32°C (90°F). Jacket water heaters can maintain this temperature. 2. The Engine Control Switch must be in the Automatic Start position. In this position, the engine will automatically start when remote starting contacts are closed. When used together with an Automatic Transfer Switch, the engine can be signalled to start and the load automatically transferred when commercial power fails. When commercial power is restored the Automatic Transfer Switch will automatically transfer the load back to the commercial power, provide a cool down time and shutdown the engine.In the Automatic Start position, the engine will automatically stop if the engine has a fault. The optional, or programmed Cool Down Timer will allow the engine to run unloaded at rated speed before shutting down.Standby Sets
If the generator set is used for a standby application with a remote transfer switch, place the Engine Control Switch in the Automatic position and adjust speed for proper operation of the generator with load after starting.Stopping the Engine
To stop the engine manually using the Automatic Start-Stop Control Panel, place the Engine Control Switch in the Stop position. If the Engine Control Switch is left in the Automatic position, the engine will stop automatically when the remote starting contacts open and the timed cool down cycle is complete (if equipped with cool down timer).Engine Shutdown Caused By Faults
The Automatic Start-Stop Module may be equipped with engine protective devices. The shutdowns will protect the engine if a malfunction occurs that causes low oil pressure, high coolant temperature, engine overspeed, or an overcrank condition. When a fault occurs and the engine shuts down, one of the fault indicators will light.Restarting the Engine
To restart the engine after a shutdown caused by a fault condition, perform the following:1. Turn the Engine Control Switch to Stop position.
Accidental starting of the engine can cause personal injury. To prevent accidental starting, disconnect the batteries before performing maintenance or repair work.
2. Correct the fault condition that caused the shutdown.3. Rotate the Engine Control Switch to the Off-Reset position.4. Make sure that the Emergency Stop buttons located on the generator set control panel and the engine junction box are reset.5. Make sure that the Air Shutoff Lever located at the top of the air inlet housing is reset (if equipped).6. The system is ready to start if the Engine Control switch is turned to Manual or Automatic. For additional information refer to the SR4 Generator mounted Control Panel module, Form SENR4027. This module is contained in the Electric Set Generator Manual, Form SENR7958.
